Bro I bought my xbox from you in May 2009 and I'm not sure which firmware u used for my xbox, but rite now I can't play new Wave 4 games like Tekken 6, COD Modern Warfare 2 and other latest games. So I want to know do you have the latest ixtreme firmware to fix this prob bro? If so, what is the version of ixtreme that u're using now? And how much is the price for updating firmware?
Thanks bro.
